[xmonad] Unmarking modules 'Unstable' in contrib

Hello, Most (152/159) modules are marked as unstable in contrib. A good number of these 'unstable' modules have not been modified since a number of releases. Here's a rough total number of modules with a last-modified date (per year):

(for x in `find .`; do; (darcs changes $x | tail -n 2 | head -n 1); done) > lastmod for x in {2007,2008,2009}; do; grep $x lastmod | wc -l; done 64 43 17

I wouldn't trust those numbers, since the total falls short of 159, but the point still stands: many so-called unstable modules have not changed in a long time, which could make it difficult for users to avoid modules that may actually change. Does anybody mind if I change the oldest modules (unchanged since 1.5 years) to be stable? -- Adam
